Patent number: 9876839Abstract: Systems, methods, and other embodiments associated with data stream classification are described. One example method includes identifying packets associated with the data stream. The example method may also include updating a set of characterization data associated with the data stream based on information associated with a packet. The example method may also include assigning a data stream classifier to the data stream by comparing characterization data to identification data upon determining that the set of characterization data indicates that the data stream is able to be classified. The example method may also include providing a signal associated with the data stream classifier.Type: GrantFiled: June 7, 2017Date of Patent: January 23, 2018Assignee: Cisco Technology, Inc.Inventors: Cetin Seren, Jisheng Wang, Sharad Ahlawat, Yingqi Xu, Vijaya Sarathy Kasi

Patent number: 9178783Abstract: Techniques for measuring network performance using the inter-packet gap metric are described. According to one approach, a computer-implemented method comprises a plurality of inter-packet gap buckets, along with their associated counts and inter-packet gap value ranges, being created and stored at a network node. Two or more network packets are received at a network node as a part of at least one unidirectional flow. For each successively received packet, the network node then determines the inter-packet gap value. Next, the network node compares the inter-packet gap value with the different discrete inter-packet gap value ranges that are associated with the stored inter-packet gap buckets. If the inter-packet gap value is included in an inter-packet gap value range associated with a particular inter-packet gap bucket then the that bucket is updated. The network node then exports the inter-packet gap metric data to a computer system.Type: GrantFiled: December 18, 2013Date of Patent: November 3, 2015Assignee: CISCO TECHNOLOGY, INC.Inventors: Yan Sun, Vivian Xu, Sharad Ahlawat, Kuntal Daftary

Patent number: 7650635Abstract: A method of preventing an attack on a network, the method comprising the computer-implemented steps of receiving an ICMP packet that includes a copy of a header associated with a connection in a connection-oriented transport protocol; obtaining a packet sequence value from the header; determining if the packet sequence value is valid; and updating a parameter value associated with the transport protocol connection only if the packet sequence value is determined to be valid. Use of the disclosed method enables authenticating ICMP packets so that responsive measures of a network element, such as adjusting an MTU value, are performed only when the ICMP packet is determined to be authentic.Type: GrantFiled: April 7, 2004Date of Patent: January 19, 2010Assignee: Cisco Technology, Inc.Inventors: Amol Khare, Mitesh Dalal, Anantha Ramaiah, Sharad Ahlawat
